Nomos Bedrock Services §

Research §

• Blend Network:

  • Statistical mechanics of anonymous communication sender anonymity analysis for simple scenario with two sender nodes, one mix node, and one receiver node
  • Minimum entropy S(O)=0 when message timelines do not overlap enabling adversarial mapping
  • Maximum entropy S(O)=1 when message timelines overlap preventing adversarial mapping
  • Average entropy E[S(O)] approaches ⅔ for large discrete time sets with de-anonymization probability approaching 1/3
  • Analytical framework development planned for k sender nodes with mix node scenarios
  • Blend Protocol Session Transition Period generalized description extended to cover epoch transitions

• Data Availability:

  • NomosDA Rewarding wording improvements and clarification for empty opinion vector creation when opinions cannot be gathered

Development §

• Blend Network:

  • Blend->chain leader dependency for private PoL info merged
  • Pre-computed winning PoL slots implementation for Blend and interested consumers near merge
  • Blend->chain leader dependency for public PoL epoch info implementation ready for merge

• Data Availability:

  • Opinion aggregator merged with SDP Activity Proof helper methods
  • Provider ID to peer ID mappings storage for opinion vector formation
  • Sorted provider ID based opinion vectors with empty byte support for session 0
  • Opinion aggregation PRs finalization in progress
